			Purpose: To allow JSF-specific content assist to be hosted
			in relevant attribute value within the JSP editor.

			The bug <a class="external" href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=130041"> 130041</a>
			logs the proposed  change request to support content
			assist for JSF EL in the JSP editor including a patch for
			the existing configuration. Proposal:

		Summary: <br>
			1) For expression language (EL) attribute values (those of
			the form "#{...}"), a patch would be applied to
			StructuredTextViewerConfigurationJSP.getContentAssistProcessors
			that handles the currently unhandled case for the partition
			IJSPPartitions.JSP_DEFAULT_EL2. This new logic would call
			into a new class called ContentAssistantProcessorLocator.
			This new class would use a new extension point (or
			alternatively a new provisional element of the
			editorConfiguration extension) to find all
			ContentAssistProcessors that wish to contribute to
			content-assist for late-bound (JSF) EL attribute values. JSF
			content assist would use this extension point to contribute
			it's logic. The impact to existing logic is almost nil. All
			new logic will be provided by JSF team as part of the patch.
		</p></td></tr><tr><td align="right" valign="top">
                &nbsp;
            </td><td valign="top"><p>
			NOTE: this scheme could extended in the future to support
			content assist contributors for other partition type as
			well. Most of the delta would be localized to the same
			configuration method.
		</p></td></tr><tr><td align="right" valign="top">
                &nbsp;
            </td><td valign="top"><p>
			2) For non-EL attributes the existing Model Query extension
			point would be used. While this is not a public interface,
			it was the only way found that content assist could provided
			unobtrusively for partitions not already handled by the JSP
			editor configuration.

                &nbsp;
            </td><td valign="top"><p>
			An alternative would be to add similar extension point
			support as discussed in 1), but add it for partition types
			already handled. Again, JSF team would provide all new logic
			required in this area.
